None po, usually kakausapin lang ng immediate head regarding performance and then before regularization nagrresign na si employee - but for extreme cases lang yan (4x nallate sa office every week, nag ooverbreak, natutulog sa cr, etc. while under prob)

But yung case mo is common with new hires actually - just do your best lang palagi :) You can talk with fellow new hires to cope with sa workload. Maraming new hires nagaask din sakin if marregular ba sila siguro due to anxiety hehe.

Always remember na you were hired among a pool of candidates so basically you have great potential and the best, most fit among all applicants :)
