Hello,
Urvashi.
Please remember u r dealing with human resourse/ capital an important asset , faced with a situation u have stated would require ,a polite and firm dealing to put the house in order definately not harsh one .
Simply firing [harsh dealing ] though easy way out but piggybacks cascading ill effects in the long run to the company , is no solution ,conversly informing ,counselling and deep seated understanding of human behavoiur(psychology) and the way employer(you) encourage/discouage the employees in giving their best performance for the company.
Employees will be productive assets provided they are made to feel part of the orgnisation and the ambiance prevailing in the work place , way they are encouraged or supressed to perform .

Set each one/team the target to be achived with in stipulated time , allow freedom to achive it within the company rules and regulations governing thr discipline. Develop personal rapo with each to build confidence.

Let the T L allocate the task for the day ,measure the performance ,as long as that is achived by end of the day , other aspects should not be bothering you .

You will be able to build good orgnisational work culture without compromising your company Goal/Objective. May be your new/alone to decide on such matters.
What i have stated is in general on the face of the situation narrated .


Solutions are available on long term and short term basis depending on the ground realities you need to apply the solution relevent to the situation.

Warm Regards
