Bawal yang ginagawa nila. After 1 year ng trabaho, automatic regular na ang status and would be entitled to benefits stated in the labor code kahit papirmahin pa sila mg contract. Masasabing contractual lang ang trabaho if after ng term ng contract, di na i-rerehire. Constant rehiring connotes the usefulness of the service to the company, thus entitles the employee to a regular status. So, entitled ka sa separation pay and kung anu-ano pang benefits. If after ng resignation mo, magsisimula ng magcount ang 3-year period na dapat igiit mo ang karapatan mo o money claims. After 3 years, wala na. Prescribed na. Ibig sabihin, nawala na ang karapatan mong igiit ang right mo.
