In general it is a good idea to follow the norms even if you are not covered by the standing orders
From India, Mumbai
There is no law governing the period of probation of employees or the Training/probation of trainees(whether management or commercial).
These policies are drawn by the management taking into consideration its requirement.
Of course, the probation period in different organisations vary to any term from 3 months to 1 year. Like wise the training period for management/commercial etc trainees also varies from 1 to 2 years. some organisations combine probation period with the training period while others keep both of them separate.
However, for workmen covered under the provisions of Cetified Standing Orders the same will apply.
Thanks and regards
