"Probably, this is the first time that the Prime Minister is meeting the trade union delegates before an ILC," Bharatiya Mazdoor Sangh General Secretary Vrijesh Upadhyay told PTI.
He further said, "The Prime Minister has invited the delegates for a high tea in the evening on Sunday where he is likely to exchange views on different issues raised earlier by trade unions and their 10-point charter of demands."
The two-day ILC will be inaugurated by Modi on July 20 and Finance Minister Arun Jaitley will be the guest of honour.
As per the agenda of the ILC, there will be detailed deliberations on labour laws amendments proposed or done either by the central or state governments.
The unions have strongly opposed some of the amendments that include norms related to easing retrenchment, lay offs and closure of units provision and forming unions under the proposed New Industrial Relations Code.
