Teachers Service Commission has retracted its earlier communication on more than 3,500 teachers missing April salary as result of not declaring their wealth.

Through short message service (SMS), the commission has assured teachers that it will not stop salary for employees who failed to declare their wealth.

“Please ignore posts circulating on social media purporting that TSC will stop salary for employees who did not comply with the requirements of Declaration of Income Assets and Liabilities.

The Commission will communicate to the affected employees individually when normalcy resumes,” read the message sent to teachers.

Early on, the commission through a circular had indicated that it will stop the employees’ salaries for Non-Compliance from March and April 2020 payrolls.

“Over 3,500 employees (secretariat staff and teachers) did not declare their Wealth within the stipulated deadline. Consequently, the Commission has stopped the employees’ salaries for Non-Compliance from March and April 2020 payrolls,” it reads.

Affected teachers were to be reinstated after confirmation in writing by their immediate supervisor indicating they have been in the service thus been teaching all along and the letter forwarded to the TSC headquarters.

“They are expected to have a confirmation in writing by their immediate supervisor indicating they have been in the service thus been teaching all along and the letter forwarded to the TSC headquarters,”  read part of the circular.

The move comes amid rising concerns over the miscalculated move taken by the commission in the wake of the covid-19 pandemic.

Kuppet

At the same time, the Kenya Union of Post Primary Education Teachers, Kuppet, as lashed out at the teachers’ employer for threatening to expunge over 3,500 teachers and staff from the payroll.

“It would be insensitive on the Commission’s part to be punishing teachers during this pandemic when other government departments are issuing temporary reprieves to citizens and foreigners for non-compliance with certain protocols during this crisis. For instance, the government has extended an indefinite extension for foreign nationals whose work permits have expired,” advises Kuppet.

ur suffices for people eating cooked food.

The advent of cooking enabled humans to eat more kinds of food, to devote less time to eating and to make do with smaller teeth and shorter intestines.

Some scholars believe there is a direct link between the advent of cooking, the shortening of the human intestinal track, and the growth of the human brain.

Since long intestines and large brains are both massive energy consumers, it’s hard to have both.

By shortening the intestines and decreasing their energy consumption, cooking inadvertently opened the way to the jumbo brains of Neanderthals and Sapiens. The domestication of fire was, therefore, a sign of things to come.

3. Read the Story below and then answer the questions that follows.

Once upon a time a father sent for his three sons and gave to the eldest a cock, to the second a scythe, and the third a cat.

“I am now old ,” said he, “my end is approaching, and I would fain provide for you before I die. Money I have none, and what 1 now give you seems of little worth; yet it rests with yourselves alone to turn my gins to good account.

Only seek out for a land where what you have is as yet unknown, and your fortune is made. After the death of the father, the eldest set out with his cock: but wherever he went, in every town, he saw from a far off a cock sitting upon the church steeple, and turning round with the wind.

In the villages he always heard plenty of them crowing, and his bird was therefore nothing new; so there did not seem much chance of his making his fortune.

At length it happened that he came to an island where the people who lived there had never heard of a cock and knew not even how to reckon the time.

They knew indeed if it were morning or evening; but at night if they lay awake, they had no means of knowing how time went.

“Behold,” said he to them, “what a noble animal this is! He carries a bright red crest upon his head, and spurs upon his heels; he crows three times every night at stated hours, and at the third time the sun is about to rise.

But this is not all; sometimes he screams in broad daylight, and then you must take warning, for the weather is surely about to change.” This pleased the natives mightily; they kept awake one whole night, and heard, to their great joy, how gloriously the cock called the hour, at two, four and six o’clock. Then they asked him whether the bird was to be sold, and how much he would sell it for.

“About as much as an ass can carry,” said he.

“A very fair price for such an animal,” cried they with one voice; and agreed to give him what he asked. When he returned home with his wealth, his brothers wondered greatly; and the second said, “ I will now set forth likewise, and see if he can turn my scythe to as good an account.”

There did not seem, however, much likelihood of this; for go where he would, he was met by peasants who had as good a scythe on their shoulders as he had. But at last, as good luck would have it, he came to an island where the people had never heard of a scythe; there, as soon as the com was ripe, they went into the fields and pulled it up; but this was very hard work and a great deal of it was lost.

The man then set to work with his scythe; and moived down their whole crop so quickly, that the people stood staring open-mouthed with wonder.

They were willing to give him what he asked for such a marvelous thing; but he only took a horse laden with as much gold as it could carry.

Now the third brother had a great longing, to go and see what he could make of his cat. So he set out; arid at first it happened to him as it had to the others, so long as he kept upon the main land, he met with no success; there were plenty of cats eve vhere, indeed too many, so that the young ones were for the most part, as soon as they came into the world, drowned in the water.

At last he passed over to an island where, as it chanced most luckily for him, nobody had ever seen a cat; and they were ovemin With mice to such a degree, that the little ivretches danced upon the tables and chairs, whether the master of the house were at home or not.

The people complained loudly of this grievance; the King himself knew not how to Find him self of them in his palace; in every conner mice were squeaking, and they gnawed everything that their teeth could lay hold of.

Here was a fine field for Puss — she soon began her chase and had cleared two rooms in the twinkling 01 an eye; when the people besought their King to buy the wonderful animal, for the good of the public, at any price.

The King willingly gave what was asked – a mule laden with gold and jewels; and thus the third brother returned home with a richer prize than either of the others. Meanwhile the cat feasted away upon the mice in the royal palace, and devoured so many that they were no longer in any great numbers.

At length, quite spent and tired with her work she became extremely thirsty; so she stood still, drew up her head, and cried, “Miau, Miau!” When the people heard this cry, they ran shrieking in great fright.

The King and his council decided to send a herald to the cat to warn her to leave the castle forthwith, or that force would be used to remove her. “We would far more willingly put up with the mice (since we are used to that evil), than get rid of them at the risk of our lives. ”

A page accordingly went and asked the cat whether she was willing to quit the castle. But Puss, whose thirst became every moment more and more pressing answered `Miau! Miau!” which the page interpreted to mean, “No! No!” and therefore carried this answer to the King. “Then we must try what force will do,” the King said.

So the guns were planted, and the palace was fired upon from all sides.

When the fire reached the room where the cat was, she sprang out of the window and ran away; but the besiegers did not see her, and went on firing until the whole palace was burnt to the ground.

“Why don’t you walk up straight like me?

That’s no way to grow old;

lt’s all a form of habit;

At least that’s what I’m told.”

The old man gave him a knowing look, And said,

“My dear young friend,

Have you ever examined your wheat field,

And noticed the heads that bend?

If not, just look them over As harvest time draws nigh;

You’ll find that the heads that are empty Are standing tall and high,

But the heads that count in the harvest Are filled and bending low,

Awaiting the reaper’s sickle;

Their time is short, they know.”

And as the young man passed on by,

He slowly bowed his head,

No doubt he pondered many a day

On the things that the old man said.
