If habitual absences na yan either reasonable or not then may rason si company kaya ginagawa yun.
If di ka naman masyado pala-absent kahit na umabsent ka once or twice they will still forgive you. Suspension means siguro napapadalas ang absences mo. Dont get me wrong ah. I'm not telling na kasalanan mo it's just that they're just doing what's on the contract that you signed beforehand.
You should know already that suspension would be one of the consequences if pala-absent ka.
I might say na don't leave your company yet, just do something about it next time. Make up to your boss or supervisor. Mahirap maghanap ng work sa ngayon, pandemic at wala msyado hiring.
Kindly apologize instead and promise that you won't be absent again.
